For a half- life, the formula is
A(t) = A0(0.5)^( t / t_0.5)
where A(t) is the amount of substance at time t
A0 is the initial amount of subtance
t_0.5 is the time it will reduce its amount to half
t is the time

substitute the given to the formula
A(t) = 100(0.5)^( t/6 )
so the decay factor is 0.5^( t/6 )

A year has 365 days, and a day has 24 hours. If an hour has 60 minutes and a minute has 60 seconds, how many seconds are there i
motikmotik
Ok, so we need to take 60 x 60.  That gives us 3600, which is the amount of seconds in 60 minutes.  Then we need to take 3600 x 24, to figure out the number of seconds in 24 hours (1 full day).  That gives us 86,400.  Finally, we take 86400 x 365, to determine how many seconds are in 1 full year (365 days).  That gives us the answer of <span>31536000.  Hope this helps!</span>
